Lost Dimension features a crew of 11 members of S.E.A.L.E.D. who are tasked with saving the world, but unfortunately, not all of them will make it, as some will betray you and a member must be chosen to be “erased” to advance. Here’s a video that shows how you can find the traitor.
The process is done through protagonist Sho Kasugai’s Gift of Vision that allows him to read into the future and also fragments of thoughts from different members. However, the traitor of the group changes according to how you play.
There are a few clues that can give you an idea of voices that can lead to hints on who the traitor is, but nothing is certain. By using Vision Points to use Sho’s Deep Vision ability, you’ll be able to hear their voices to determine whether they’re the traitors, or not.
In the first attempt, Sho listens to the thoughts of Himeno, but she seems determined to complete their mission, and shows no sign of harm.
You’ll also be able to have conversations with other characters, who might ask you things like who is the traitor, and you’ll have to provide an answer that may influence their choices.
Once you’re done, the party will be led into the Judgment Room, where it will be decided on who must be erased by a vote from all the members. In this case, they show that it is the medic Sojiro Sagara, who then congratulates them for making the right choice.
In the earlier scene, Yoko Tachibana is seen asking Sho who he thinks is the traitor, which he selected as Sojiro, and likely determined the outcome of the vote. Again, depending on who you play and who you use more during missions, the traitors will vary.
Lost Dimension is slated for release in Japan on August 7, 2014 for PlayStation 3 and PlayStation Vita.
